Meningioma

Abstract

Intracranial meningiomas present a variety of management challenges due to their indolent growth when WHO I, their uncertain behavior when WHO II, and their lack of response of any form of therapy when WHO III. Additionally, there is no effective chemotherapy for those with malignant and recurrent behavior. Stereotactic Radiosurgery (SRS) and Stereotactic Radiotherapy (SRT) came to aid the treatment of meningiomas, avoiding the side effects of conventional radiation therapy and allowing for escalation of radiation dose. Outstanding tumor control rate has been achieved when using these techniques as primary or adjuvant treatment. As a result it has allowed partial resections for function preservation, since the control rate of residual meningioma treated with SRS or SRT is similar to what can be achieved by complete resection.​
